First prototype of the new "signal-processing-module". 9 dual opamps doing:
- bal-input/output
- line-buffer
- 4.th order filters at 40Hz, 160Hz and 2.2Khz
- Notch-filter at 16KHz.
Also included is a simple mute-circuit.
Surprisingly it all appears to be working.

An externally hosted image should be here but it was not working when we last tested it.
Great project dude...
Maybe one advice from me
Using big cable for power supply transformer, bridge rectifier and output to speaker
My experience small cable getting warmer than hot cable
I use many big cable for my amplifier, speaker and some devices have been repairing by me(changing default cable)
